ORDER AND JUDGMENT *
Tommie Perris Crawford, a federal prisoner proceeding pro se,1 seeks a certificate of appealability (COA) to appeal the district court’s denial of his Fed. R. Civ. P. 60(b) motion. Crawford also seeks leave to proceed on appeal in forma pauperis (IFP). We deny Crawford’s request for a COA, deny his IFP motion, and affirm.
Crawford was convicted in the United States District Court for the District of Minnesota and is currently incarcerated in the United States Penitentiary in Leavenworth, Kansas. Crawford initiated this civil proceeding in state court by filing a petition to enforce a “Satisfaction of Judgment.” R. vol. 1, 8-9. Crawford identified the plaintiff in the purported in rem proceeding as “a foreign state and international organization” and sought release of that organization’s property — i.e., Crawford — under a theory of immunity. Id. The government removed the case to federal court and sought dismissal.
The district court construed Crawford’s petition as an attack on his federal sentence. The court first noted that if Crawford intended to file a 28 U.S.C. § 2255 motion he should have done so in the district that imposed his sentence. The court then pointed out that, in limited circumstances, a federal prisoner may challenge the legality of a federal sentence in the district of incarceration under 28 U.S.C. § 2241. The court recognized that Crawford didn’t invoke either § 2241 or § 2255 in his petition. The court neverthe*575less concluded that even if it construed the petition as one seeking relief under § 2241, Crawford failed to demonstrate that he was entitled to such relief. The court ultimately dismissed Crawford’s claim as legally frivolous.2
Crawford then filed a Rule 60(b) motion seeking relief from the district court’s dismissal order and asserting for the first time that he should be allowed to proceed under § 2241(c)(4) -because his remedy under § 2255 was ineffective and inadequate. See 28 U.S.C. § 2255(e) (permitting a federal prisoner to apply for relief under § 2241 only if § 2255 remedy “is inadequate or ineffective to test the legality of his detention”); Abernathy v. Wandes, 718 F.3d 538, 547 (10th Cir. 2013) (explaining that § 2255 remedy “has been found to be ‘inadequate or ineffective’ only in ‘extremely limited circumstances’ ” (quoting Caravalho v. Pugh, 177 F.3d 1177, 1178 (10th Cir. 1999))).
The district court construed the Rule 60(b) motion as one seeking relief under § 2241 through § 2255(e)’s “savings clause,” concluded Crawford failed to demonstrate that the remedy provided by § 2255 was inadequate or ineffective merely by asserting such a motion would be time-barred or potentially subject to filing restrictions in the district of his conviction, and denied relief. The district court also denied Crawford’s motion to proceed IFP on appeal.
Crawford renews his request for leave to proceed IFP on appeal, and asks us for a COA to appeal the denial of his Rule 60(b) motion. For the following reasons, we deny both requests and affirm the district court’s ruling.
We decline to issue a COA because Crawford doesn’t need one. The district court construed Crawford’s Rule 60(b) motion as a § 2241 application and determined Crawford failed to demonstrate he could invoke § 2255(e)’s “savings clause” to attack the validity of his federal sentence under § 2241. A federal prisoner doesn’t need a COA to appeal a final judgment in a § 2241 case. Eldridge v. Berkebile, 791 F.3d 1239, 1241 (10th Cir. 2015). And we affirm the district court’s ruling because we agree that Crawford hasn’t demonstrated — simply by asserting his ability to file a § 2255 motion is barred by timing or filing restrictions — that his case presents one of those “rare instances” in which a federal prisoner may use § 2241, rather than § 2255, to attack the validity of his federal sentence. Sines v. Wilner, 609 F.3d 1070, 1073 (10th Cir. 2010); see, e.g., Haynes v. Maye, 529 Fed.Appx. 907, 910 (10th Cir. 2013) (unpublished) (noting fact that § 2255 motion is time-barred doesn’t render § 2255 remedy inadequate or ineffective); Garris v. Lindsay, 794 F.2d 722, 727 (D.C. Cir. 1986) (“It is the inefficacy of the [§ 2255] remedy, not a personal inability to utilize it, that is determinative, and appellant’s difficulty here is simply that his circumstances preclude him from invoking it.”).
Finally, we deny Crawford’s IFP motion because his appeal is clearly frivolous. See DeBardeleben v. Quinlan, 937 F.2d 502, 505 (10th Cir. 1991) (noting that to succeed on IFP motion, movant must show “a reasoned, nonfrivolous argument on the law *576and facts in support of the issues raised on appeal”).
